Golly... thanks for all the help. It is my understanding that a concourse correct dual redline tire is not available in the after market ? Things change and I could be wrong ? Rockhouse and Lancelot66's using/suggesting Diamond Back is certainly an option. I think the tire I posted is a more affordable, $200 and free shipping, option ? That tire is from Coker # 530293, is a BF Goodrich tire, with all the usual tire info, ratings, approvals, warranties and has the 3/8" dual red stripes factory installed. At the moment it seems if I want a dual red stripe tire and a radial performance tire this might be it ? Kinda exploring the subject at the moment and learning. Thanks, Brian
